I had a parakeet for a little under a year. One day he flew into some walls. When I was getting off work later that day I got a call from my Dad that he had run into a wall again, but this time he wasn't moving very much. He died shortly after I got home. He didn't usually run into walls.was he sick. What could we have done? I am planning on getting another parakeet but I don't want to make the same mistake. What should I do? Thanks.
